🟧 CKA 2025 — Q-04
Install Argo CD in the cluster:
- Add the official Argo CD Helm repository with the name argo.
- The Argo CD CRDs are already pre-installed in the cluster.
- Generate a Helm template of the Argo CD chart version 7.7.3 for the argocd namespace and save it to /argo-helm.yaml.
- Configure the chart not to install CRDs.
- Install Argo CD using Helm with release name argocd, using the same version (7.7.3) and the same configuration used in the template.
- Install it in the argocd namespace and configure it to not install CRDs.
- You do not need to configure access to the Argo CD UI.
✅ Solution (CKA Fast-Execution Style)
1️⃣ Add the Argo Helm repo
helm repo add argo https://argoproj.github.io/argo-helm
helm repo update
2️⃣ Create the namespace
kubectl create ns argocd
3️⃣ Generate Helm template WITHOUT CRDs
Save output → /argo-helm.yaml Chart version → 7.7.3 Namespace → argocd
helm template argocd argo/argo-cd \
--version 7.7.3 \
--namespace argocd \
--set installCRDs=false \
> /argo-helm.yaml
4️⃣ Install Argo CD using Helm (same settings)
Release name: argocd
helm install argocd argo/argo-cd \
--version 7.7.3 \
--namespace argocd \
--set installCRDs=false
